Hi Scott, Attached are the Delta row settings for the wire measurements. I suggest you start with the linear polarization vertical field mode. Let's start with just the kind=1 positions. In this case, you measure at just 6 K/K0 settings. For each value of K/K0, perform the following measurements: 1) Measure the first integral of Bx on the centerline. 2) Measure the first integral of By on the centerline. 3) Measure the second integral of Bx on the centerline. 4) Measure the second integral of By on the centerline. 5) Measure the first integral of both Bx and By on the x-axis at y=0, x = -1.2, -.8, -.4, 0, .4, .8, 1.2 mm. Compute the slopes of lines fit to the data which give the skew quadrupole and normal quadrupole integrated gradients. 6) Measure the first integral of both Bx and By on the y-axis at x=0, y = -1.2, -.8, -.4, 0, .4, .8, 1.2 mm. Compute the slopes of lines fit to the data which give the normal quadrupole and skew quadrupole integrated gradients. Let me know if there are any problems making these measurements. Please start with these measurements and then let's stop and see how long they are taking. Heinz-Dieter and Yurii then have time to add input before you proceed. Zack
